So... why wouldn't this show up consistently in the EGM96 data? EGM96 is a definition of Earth's equipotential height constructed by measuring it with satellites like GRACE. Its as close to a definition of true sea level as you're going to get. But it doesn't have this kind of consistent uplift near tall masses throughout the model. The Southern Ocean's height is sinusoidal about Antarctica. We do see an increase in equipotential height in the Andes, and in the eastern Pacific nearby. But near the Himalayas the equipotential height is lower. https://en.wikipedia.org/wiki/File:Earth_Gravitational_Model_1996.png https://en.wikipedia.org/wiki/File:Earth_Gravitational_Model...
